Cardiogenic shock typically is triggered by a heart attack, and is definitely life-threatening. Even with treatment, it ends in death 65 to 80 percent of the time. Cardiogenic shock is characterized by a decreased pumping ability of the heart that causes a shocklike state with inadequate perfusion to the tissues.
Cardiogenic shock results from the inability of the heart to pump blood through the body. Cardiogenic Shock is the most serious consequence of myocardial infarction, but can also result from other cardiac emergencies, such as cardiac tamponade. A sudden and severe drop in the blood pressure and blood flow through the body because the heart is not pumping normally.Cardiogenic shock caused by cardiac arrest. Cardiogenic shock is based upon an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively The usual cause is myocardial infarction. However, there are some noncoronary causes such as cardiomyopathy, valvular heart abnormalities, cardiac tampanade, or cardiac arrhythmias. These patients would generally have poor cardiac output. Clinically they will have tissue hypoxia resulting in oliguria, cyanosis, altered mentation, and cool extremities. The patient may require intraaortic balloon pump therapy, ventricular assistive device, or might ultimately require cardiac transplant. Systolic BP < 90 mm Hg, or 30 mm Hg below baseline for at least 30 mins, evidence of poor tissue perfusion and persistence of shock after correction of non-myocardial factors (eg hypovolaemia, hypoxia, acidosis, arrhythmias)
Acute hypoperfusion of the tissues and organs, usually with associated hypotension, due to a primary failure of the pump action of the heart, where the circulating blood volume is adequate. Cardiogenic shock occurs when the heart is unable to pump blood and maintain an adequate blood supply for other vital organs. Cardiogenic shock has a death rate of about 60% and is the major cause of death in patients hospitalized for a heart attack. Getting immediate medical treatment for a heart attack is important in preventing the development of cardiogenic shock. Commonest cause is myocardial death/stunning after infarction or critical ischaemia.

Treatment of Cardiogenic Shock
Dopamine, dobutamine, epinephrine, norepinephrine, amrinone, or other medications may be required to increase blood pressure and heart functioning. Pain medicine may be given if necessary. Bed rest is recommended to reduce demands on the heart.The patient may require intraaortic balloon pump therapy, ventricular assistive device, or might ultimately require cardiac transplant. Because of the heart's inability to deliver sufficient oxygen-rich blood to the tissues, the doctor will boost your oxygen supply. It is given either through a mask or nasal prongs.
